Safety and protection is the requirement of every house, industry, organization, etc. Wireless Photoelectric Smoke D1700101 detector helps us in detecting smoke so that we are aware and conscious of our environment.
Function
Audible and Visual Alarm Indicators
When operating normally, a red LED adjacent to the Test button will flash every 320 s. When smoke is detected, an internal sounder will activate to alert occupants, and the LED will flash rapidly. The sounder is a loud, pulsating alarm and produces a repeating Temporal 3 audible signal pattern (0.5 s on, 0.5 s off for 3 cycles, followed by 1.5 s off, repeating).
Test/Hush Button
When there is no alarm present, hold the Test/Hush button will activate the smoke alarm to check its operation. The alarm will sound and the LED will flash rapidly. The unit will return to normal condition in about 10 s when the test is completed.
When the smoke alarm is in the Alarm condition, press the Test/Hush button will hush the smoke alarm for approximately 11 min. The Hush feature should only be used after the cause of the alarm is known (such as normal cooking fumes). The Hush feature allows time for the smoke to clear. During the hush time, the LED will flash twice every second. After the Hush time has expired, the smoke alarm will return to normal sensitivity. If smoke is still present in the unit, the alarm will re-activate. The Hush feature can be used repeatedly.
Smoke Chamber Fault
The detector monitors the condition of the smoke sensing chamber. If the smoke sensing chamber ceases to operate normally, the smoke alarm will emit a short audible signal, then followed by a single Red LED indicator flash, repeating every 40 s. In this case, try vacuuming clean the detector to remove dust. If the condition persists, replace the detector with a new unit.
Low Battery
When the battery is depleted, the detector will emit a short audible signal and the Red LED indicator flash, repeating every 40 s for at least 30 days. Interconnected detector will also emit two short audible signals and the Red LED indicator will flash twice, repeating every 4 hours. When the Low Battery signal is given, replaced the detector with a new unit.
Interconnection
Wireless interconnection allows up to 12 detectors to be connected together. Interconnected detector will activate sounders on all units if any smoke alarm detector. In this case, only the detector that detected smoke will flash the Red LED. This allows the home owner to quickly locate the cause of the alarm.
Local alarm memory
After alarm occurs, the green LED gives 3 flashes every 40 s up to 24 h, which stops flashing after 24 hours. Any time before the next alarm, press the Test button, the detector shall emit 3 audible beeps every 1 s. Release of the Test button shall reset the alarm.
Installation:
Equipment
Before commencing installation, ensure all equipment and tools to mount and test the device are available, such as drills, mounting screws (supplied), cables and ladders.
Location Selection
- Location and number of smoke alarms may be specified in relevant regulations. Where these do not exist, the requirements of DIN 14676 can be used.
- According to German application standard DIN 14676
Note:
- Smoke alarm are to be used as minimum requirement in all bedrooms, children’s rooms and hallways which act as escape routes, and are to be installed in each case in the middle of the room, on the ceiling only (do not install on wall). Select the installation location with a minimum distance of 50 cm to surrounding walls, furniture and lamps.
- Configuration is optimal when devices are also located in all other rooms as well as staircases.
- In kitchens and wet rooms, smoke alarms are only used when false alarm caused by the characteristics of these space are excluded. Please observe the graphics in this guide.
Where Not to Install the Smoke Detector:
Nuisance alarms occur when smoke alarms are installed where they will not work properly. To avoid nuisance alarms, do not install smoke alarms in the following situations.
- In or near areas where combustion particles are present, such as kitchens with few windows or poor ventilation, garages where there may be vehicle exhaust, near furnaces, combustion heaters, and space heaters. Combustion particles are the by-products of something that is burning, which the smoke alarm may detect.
- Within 6 m of kitchens where combustion particles are normally present. If a 6 m distance is not possible, e.g. in a mobile home, try to install the smoke alarm as far away from the combustion particles as possible. Ensure the area is well ventilated.
- In dead-air areas, where ventilation systems cause air-flow that would not pass through the smoke alarm sensing chamber. Avoid also air-flow from areas where normal combustion particles are expected, such as kitchens.
- In damp or very humid areas, or within 3 m of bathrooms with showers. Moisture in humid air can enter the sensing chamber, then condense into droplets upon cooling, which can cause nuisance alarms.
- In very cold or very hot areas, including unheated buildings or outdoor rooms. If the temperature rises above or falls below the operating range of smoke alarm, it may not function properly. The temperature range for your smoke alarm is -10 °C ~ 60 °C.
- In very dusty or dirty areas. Dirt and dust can build up on the smoke alarm’s sensing chamber, to make it overly sensitive. Additionally, dust or dirt can block openings to the sensing chamber and limit the smoke alarm from sensing smoke.
- Near fresh air vents or high draft areas like air conditioners, heaters or fans, fresh air vents and drafts, which can drive smoke away from smoke alarms.
- In dead air spaces, which are often at the top of a peaked roof or in apex of ceilings and walls. Dead air may prevent smoke from reaching a smoke alarm. See Fig. 2, Fig. 3, Fig. 4 and Fig. 5 for recommended mounting location.
- In insect-infested areas. If insects enter a smoke alarm’s sensing chamber, they may cause a nuisance alarm. Where insects are a problem, get rid of them before installing the smoke alarm.
- Near fluorescent lights. Electrical “noise” from fluorescent lights may cause nuisance alarms. Do not install smoke alarms within 1.5 m of such lights.
Operations:
Once installed and tested, the detector will immediately start monitoring for smoke. If the sounder in the detector operates, check for a fire and execute your safety plan.
If the detector was caused by a nuisance situation, open a window or fan the air to remove the smoke or dust from within the smoke detector. The detector will turn off as soon as the air is completely clear. Do not disconnect the battery to silence the smoke detector.
Hush
Before using the Hush feature, identify the source of smoke and be certain that safe conditions exist.
If investigation shows the alarm signal is likely caused by a known nuisance source (such as cooking fumes), the Test/Hush button can be pressed to silence the smoke alarm for 11 min.
After the Hush time has expired, the smoke alarm will return to normal sensitivity. If smoke is still present, the alarm will be re-activated. The Hush feature can be used repeatedly.
